What I love most about gardening is there's always new-to-you stuff to learn. I love to try something and see what happens.
Last week I went to a talk by Janet Macunovich at the Dexter Garden Club. It was fun looking at photos of pretty plants and getting Janet's take on the mixed perennial border. Then, as an aside, she mentioned an alternative to overwintering tender bulbs (cannas, dahlias, and gladiolas†) inside: You can bury them deeper (at least 18 inches) in the garden instead!
I left some glad bulbs in the ground to die last faIl. I'd gotten them really cheap and was treating them as annuals. But what the hey! Our soil isn't frozen solid, so I decided to give burying the bulbs deeper a try.
Fortunately, I didn't cut the gladiola foliage to the ground in fall, so I could actually tell where the bulbs were.
I decided to dig the storage hole in my veggie bed because that's empty over winter, and the soil there is easier to dig than my less-amended clay soil in other beds. It was pretty easy digging until about a foot down. I always forget the huge tree roots everywhere in my garden. This particular one was only an inch in diameter (a mere baby!), but required getting out the big pruners.
I live near a wooded natural area. This part of it is not 15 feet from the veggie bed. You're seeing mostly buckthorn, which has crazy long roots, but the biggest diameter roots come are from the many nearby 30-plus-feet-tall trees.
After digging the storage hole to about 21 inches, I went to dig up the glads. They were only maybe 6 inches down and not hard to reach at all. Most of the bulbs had starting multiplying and had baby bulbs on the sides. Aww...
I wished I had a mesh bag to put the bulbs in so I could easily pull them all up at once in spring, instead of digging around onesy-twosy. Then it dawned on me I had this decorative metal basket I got at a yard sale but never figured out how to use. So I put all the bulbs in that and set it into the base of the hole.
A more shallow, wider mesh basket that could hold a single layer of bulbs might have been nicer in terms of drainage, and I contemplated jerry-rigging something out of metal fencing, but that would also have meant digging a much wider hole and I was done fighting with roots.
I filled all the soil back into the hole and topped the area with some pine needles for extra protection. Pinestraw tends to stay put (not blowing away in the wind or decomposing over winter), but just to be on the safe side (mark twice, dig once!), I stuck a locator stake in the ground just behind the basket of bulbs.
In spring, I'll dig them up and move them back to the front garden bed at their normal desired planting depth. The storage hole is only to provide the bulbs with more warmth to survive the winter. If I left them that deep in spring, it would take them forever to reach the surface.
Well that's that. Now we'll see what happens!
